Abstract :
The authentication system on Android devices
aims to ensure that only the rightful owners of the
devices get access to them. This work tested the usability
of increasing the size of PIN from the conventional 4
digits to 5 digits using a specially designed Android app.
We experimented with the scheme with 104 volunteers.
Although only 2.88% of the respondents did not
authenticate successfully after the allowable 3 retries,
41.45% of the users succeeded only after the third
attempt. The average authentication time was 9 seconds.
